ElasticSearch close restart command

From: http://www.cnblogs.com/ae6623/p/5110927.html

Many people learn elasticSearch by self-study. There is no answer to Baidu's question of how to restart es. I'm trying to figure it out. I hope I can help you.

1. How to close ES and elasticsearch

1. Use the head plug-in

Find the node you want to shut down and shut down

2. Use the command kill to kill the ES process of the server

1. Find ES process

ps -ef | grep elastic

2. Kill ES process

kill -9 2382 (process number)

3. Restart ES

sh elasticsearch -d

2. How to restart ES

There is no way to restart. Only refer to close - > open above.

The following is the detailed operation process

1. First, check whether there is an ES process on the server. If the ES process is not turned on, you don't need to turn it off. If it is turned on, kill the process

1. Find the process command ps -ef | grep elastic
[root@bjdhj-125-203 _site]# ps -ef | grep elastic

//Then you can see the following process number,2382,2583 After thatkillJust drop it.

2. Kill the process kill-9 2382 (process number)
//Kill kill kill kill all. If you are not sure about the process number, you can check the process path address in the above information to prevent the error

[root@bjdhj-125-203 _site]# ps -ef | grep elastic
